为了制定裸眼3D 关键指标的标准化测试方案，本文根据目前主流的自由立体显示和指向性背光技术的不同显示原理及其甜点的不同排列情况，分别设计了不同的测试方法，并对其进行串扰率、亮度、对比度、色温、色域等关键指标的完整测量与评价。测试结果表明，指向性背光式裸眼3D 显示器的串扰率低达2．64％，远低于柱镜式(80．91％)和液晶光栅式(3．3％)裸眼3D 显示器；亮度、色域、色温等指标上，指向性背光式显示也胜于柱镜式和液晶光栅式技术；而在对比度上，柱镜式裸眼3D 显示凭借较佳的亮度，取得最优秀的数值，明显强于液晶光栅式和指向性背光技术。
In order to set up a standard for evaluating key properties of autostereoscopic display, crosstalk ratio,luminance,contrast,color temperature and color gamut are measured according to different displaying principles.As the measurement result shows,in terms of crosstalk ratio,direc-tional-backlight autostereoscopic display is superior to lenticular-lens (80.91%)and barrier (3.3%) autostereoscopic display with the lowest crosstalk ratio of 2.64%.Besides,directional-backlight au-tostereoscopic display outclasses the other two kinds of displays in luminance,color gamut and color temperature.However,in the aspect of contrast,lenticular-lens autostereoscopic display surpasses the other two types of displays with the best value.
